Reset timer

Claim 2

In a timing device, a control device having an actuating element, a timing gear having a bearing about which it rotates, a drive gear arranged for engagement with the timing gear for driving the same when the gears are engaged, spring means for driving the timing gear when the gears are disengaged, means including an operator carried by said timing gear for moving the actuating element of the control device when the timing gear is driven to a predetermined angle of rotation, and means for disengaging the gears laterally for allowing movement of the timing gear by the spring means, said disengaging means bodily carrying said bearing and moving the timing gear laterally away from the drive gear said drive gear being yieldably supported and movable in a direction in which the driving force pulls it into engagement with the timing gear, and allows advancing of the timing gear faster than driven by the drive gear.

Claim 3

The combination recited in claim 1 in which the disengaging means moves the bearing in a direction causing the engaging gear teeth on the timing gear to move substantially radially from the engaging gear teeth on the drive gear, thereby separating the gears without rotation of the timing gear.

Claim 4

In time control means, the combination of, a control device having an operator, said control device assuming one control position when the operator is in a first position and assuming a second control position when the operator is in a second position, timing means, a motor, motion transmitting means between the timing means and motor including clutch means, means controlled by the timing means when the clutch means is engaged for actuating said operator from said first position to the second position when the timing means reaches timed out position, electro-magnetic control means having a first position and a second position, means actuated when the electro-magnetic means is in its first position to engage the clutch means and to disengage the clutch means on movement of the electro-magnetic means to its second position, and means actuated on movement of the electro-magnetic means to said second position for holding said switch operator in its second position independently of the timing position of the timing means.

Claim 5

In time control means, the combination of, a control device having an operator, said control device assuming one control position when the operator is in a first position and assuming a second control position when the operator is in a second position, timing means, a motor, motion transmitting means between the timing means and motor including clutch means, means controlled by the timing means when the clutch means is engaged for actuating said operator from said first position to the second position when the timing means reaches timed out position, electro-magnetic control means having a first position and a second position, means actuated when the electro-magnetic means is in its first position to engage the clutch means and to disengage the clutch means on movement of the electro-magnetic means to its second position, and means actuated on movement of the electro-magnetic means to said second position for holding said switch operator in its second position independently of the timing position of the timing means.

Claim 6

The combination recited in claim 3 in which the control device includes a switch having a control effect on the electro-magnetic means.

Claim 7

The combination recited in claim 3 in which the control device includes a switch which is caused to be open either by the timing means in its timed out position or by the electro-magnetic means being deenergized, the switch closing when the electro-magnetic means is energized, and circuit means whereby closure of the switch maintains the electromagnetic means energized.

Claim 8

In a timing device, timing means, a motor, motion transmitting means including a clutch between the timing means and motor for driving the timing means in one direction when the clutch is engaged, spring return means for driving the timing means in the opposite direction when the clutch is disengaged, a control device, said control device having a spring biased operator which is moved against its bias by movement of the timing device to timed out position due to the clutch being engaged, means for operating the clutch to disengage it allowing return of the timing means by its spring return means, and means for holding the operator against its bias when the clutch is disengaged.

Claim 9

In a timing device, timing means, a motor, motion transmitting means including a clutch between the timing means and motor for driving the timing means in one direction when the clutch is engaged, spring return means for driving the timing means in the opposite direction when the clutch is disengaged, a control device, said control device having a spring biased operator which is moved against its bias by movement of the timing device to timed out position due to the clutch being engaged, means for operating the clutch to disengage it allowing return of the timing means by its spring return means, and means for holding the operator against its bias when the clutch is disengaged.

Claim 10

The combination set forth in claim 6 in which a single lever actuates both the clutch operating means and the holding means.

Claim 11

The combination set forth in claim 6 in which a single lever bodily carries both the clutch operating means and holding means.

Claim 12

The combination set forth in claim 6 in which the holding means is arranged to hold the operator before the clutch operating means disengages the clutch.

Claim 13

In a combination delay timer and interval timer, the combination of, spring return timing means, a motor, motion transmitting means including a clutch connecting the motor and timing means for driving the timing means in one direction when the clutch is engaged, means for driving the timing means in the opposite direction when the clutch is disengaged, a control device, means for actuating said control device in one direction when the timing means reaches a predetermined position, means including an electro-magnetic controller for engaging or disengaging the clutch, and means actuated by the controller on disengaging the clutch for holding the control device in said one direction, said last named means being arranged for field disablement for field converting the timer from an interval timer to a delay timer.

Claim 14

In a combination delay timer and interval timer, the combination of, spring return timing means, a motor, motion transmitting means including a clutch connecting the motor and timing means for driving the timing means in one direction when the clutch is engaged, means for driving the timing means in the opposite direction when the clutch is disengaged, a control device, means for actuating said control device in one direction when the timing means reaches a predetermined position, means including an electro-magnetic controller for engaging or disengaging the clutch, and means actuated by the controller on disengaging the clutch for holding the control device in said one direction, said last named means being arranged for field disablement for field converting the timer from an interval timer to a delay timer.
